  • HadFrame System
  • HadFrame Lightweight Steel Building System

The HadFrame system allows for very rapid erection of the super structure of the house, therefore reducing time on site and costs, through using less skilled labour and modern construction methods. The light gauge steel frame is assembled in panel format, off-site, to the clients specification and delivered to site on a just in time basis, this avoids the unnecessary storage or wastage of materials. Due to being able to fill the hollow lightweight steel frame with insulation, in addition to solid external insulation the finished property will have a U value down to 0.17 or better. A steel framed property reduces the need for snagging and defects by being a much more accurate and solid construction.

Benefits of the HadFrame System:

  • Speed of construction (30% faster than traditional methods)
  • Excellent performance characteristics (thermal and acoustic)
  • High level of quality control, accuracy and freedom from shrinkage
  • Lightweight for use on poor ground with reduced foundation requirements
  • Waste recycling in manufacture and reduction of onsite waste
  • Room in roof systems can be constructed easily

The HadFrame system removes the traditional cavity and requirement for strip foundations allowing RC raft foundations and warm wall technology. Call us to find out more.

Whilst it can be used in any residential or commercial application, its strength and target audience is the housing sector. We are currently completing our accreditation under the Build Offsite Property Assurance Scheme (BOPAS) and will therefore offer a 60 year building warranty, vital for any property needing to be ‘mortgageable’.

HadFrame Lightweight Steel Building System

System Description

Manufactured in Poland by Frame Factory Sp. Z.o.o. ul Brzozowa 8A, 97-400 Belchaow, or by Frameclad Ltd., Building 33, Bay 9, Second Avenue, The Pensnett Estate, Kingswinford, DY6 7UG, factory assembled wall, floor and roof panel cassettes comprising the steel framing only are transported to site and assembled in sequence on a prepared sub-structure.

The system comprises cold-rolled galvanised lightweight steel sections ‘u’ and ‘c’ sections forming the external and internal walls, upper floors and roof panels. Internal and external walls are constructed with ‘u’ section top and bottom rails with ‘c’ section studs of size and spacing commensurate with the structural design. Stability does not rely on connections to adjoining buildings. Each unit is designed to be structurally stable within its own enclosing walls.

Durability Assessment – 60 Years

Limits of Scope

  • Maximum 6 storeys for residential use (with the incorporation of hot-rolled steelwork to achieve structural design parameters)
  • Bottom members minimum 150mm above external ground level and isolated from damp
  • Adequate sub-floor ventilation must be maintained to the void below the ground floor, in particular where there is no treatment of the ground to prevent moisture enteringthe void
  • Minimum 15mm drained cavity behind external wall claddings (if no cavity, evidence to show that no detrimental moisture accumulation will occur – e.g., testing to MOAT 22, ETAG 004 assessment, Dynamic modelling such as WUFI hygrothermal modelling)
  • HadFrame must be contracted for the design, manufacture, supply and erection of the structures
  • A chartered structural engineer suitably experienced in the design of this type of structure must be sub-contracted for the structural analysis and design
